PROGRESS IN STUDY ON ELASTIC AND ELECTRIC ANISOTROPY IN CRUST MEDIA

摘要:

分析了地壳介质各向异性研究的现状,指出了弹性和电性各向异性研究中存在的问题,提出了联合利用弹性和电性各向异性研究地球介质特征及提取物性参数的正反演方法。理论研究和地震过程的实际资料表明,将弹性和电性结合起来研究地壳介质各向异性具有清晰明确的物理意义,是各向异性研究的一个非常有发展前景的新领域。

Abstract:

The present research situation on anisotropy in crust is analysed, and the difficulties in identifing the crust anisotropy by using seismic waves and electricity each respectively are indicated. The forward and inverse methods of studing the features of crust media and extracting crust parameters by combined using elastic and electric anisotropy are intruducted. The results of theoretical and practical data show that the combined study on seismic waves and electricity for anisotropy in crust gives clear physical meaning, it will be a new development fields to research anisotropy.
